The Sun is an averaged size star so it doesn't have enough mass to explode. Instead it reheats and expands into a red giant, so earth will be vaporized within the sun! Oh yeah and don't freak out, it's not going to happen within 5 billion years. Plenty of time to get that degree and a good job, and to raise a family. In four billion years 4,000,000,000 Roughly 4-5 billion years but the Sun will not go dark for roughly 20-30 billion years.

Although the Sun will continue to shine for billions of years Earth will be uninhabitable in roughly 1 billion years this is because as the Sun ages it gets hotter and brighter and in about 1 billion years the temp on Earth will be too hot for liquid water to exist on the surface.
